The table amplifier MV-030 from RCS Audio-Systems is a compact, professional amplifier for electroacoustic loudspeaker systems (ELA). It is suitable as a central unit in voice alarm and announcement systems, where high functionality is required in a small housing. The device offers various connection options and expansion possibilities, with an integrated blank space allowing for later installation of media modules or digital control modules such as the DM-10. The design is intended for use in technical installations, with dimensions of 375 mm (width) × 88 mm (height) × 260 mm (depth) and a weight of approximately 5.4 kg.

Applications

The MV-030 is intended for professional applications in buildings, industrial plants, transport operations, or security systems, where reliable voice transmission via loudspeaker systems is required. The ability to operate the amplifier either on mains power (230 V AC) or on direct current (12 V DC) extends its application range to mobile or off-grid systems, for example using a car battery. The output power is selectable and amounts to either 30 W RMS (max. 48 W) or 60 W RMS, allowing the system to be adapted to different loudspeaker installations.

Functions and equipment in detail

The amplifier features two balanced microphone inputs, equipped with a switchable priority function to prioritize voice transmission during emergencies or alarms. Two balanced AUX inputs are available, one of which can be switched to function as a MIC input. An additional unbalanced TAPE input allows connection to recording devices. The electronically balanced inputs ensure interference-free signal transmission, even over long cable runs, which is important for professional installations. Each input has a separate volume control, allowing individual level adjustment.

Technology explained simply

The frequency response range is between 150 Hz and 18 kHz, sufficient for clear voice reproduction and adequate music playback. The total harmonic distortion (THD) at 1 kHz is less than 1 %, indicating low distortion and high signal quality. Signal-to-noise ratios are over 60 dB for the MIC input and over 70 dB for the AUX inputs, ensuring good separation between the desired signal and background noise. An equalizer with bass and treble controls (Bass: 40 Hz – 400 Hz, Treble: 2.5 kHz – 20 kHz, each –6 dB/Oct) allows targeted tone shaping. An LED level indicator with clipping warning at +3 dB displays the signal level and warns against overloading.

Compatibility and accessories

The loudspeaker outputs support various impedances: 100 V, 70 V, and 4–16 Ohm, enabling adaptation to different loudspeaker systems. The TEL IN / TEL RING connection allows connection of a telephone to enable announcements or ringtone transmission directly from the telephone network. The integrated blank space in the device is designed for installation of additional modules such as media modules or digital control modules (e.g. DM-10), thereby expanding the amplifier’s functionality.

Mounting and installation

The MV-030 is designed as a table amplifier and can be mounted on a work surface. Power supply is via 230 V AC or 12 V DC, with a maximum current draw of 0.55 A and power consumption of 125 W. Installation requires connecting the inputs and outputs according to the application, with the balanced inputs ensuring interference-free transmission. Wiring is done via standard connectors provided in the device.

Advantages in operation

Operation of the MV-030 is simple and flexible due to its clear controls and diverse input options. The priority switching ensures that important messages are always transmitted with priority. The ability to operate the amplifier on 12 V DC increases operational safety, especially during power outages. The integrated expansion option enables future-proof installation that can be expanded later without replacing the device. The LED level indicator supports operation by providing visual feedback on the signal level.
